Ok. Well here are some more pictures. I didn't want to compromise the mechanism or various bolts that were riveted/pressed together, and after looking at it for a while, I decided to compress the spring as much as I needed, to make my plan work. I didn't want to remove the plate that acts like a stopper for the notch, since this plate is also used to guide the bolt through the mechanism. I used some braided shoe strings to compress the spring since this is all I had that was both strong and thin enough to fit through the spring and mechanism. I used two strings (about 180 degrees from each other) in order to evenly compress the spring.
The plan: Since the spring is compressed, I will have room to grind down the notch to a point that I find suitable. I will be extending the notch down the bolt as far as I can. The tool that I will be using is a grinder.
In the pictures below you will see the stopping plates that I'm referring to.
In picture 2 you can see the plate that is used to stop the bolt with the notch. The plate is running horizontal, has two strings tied to it, has some serial number etchings, and is right above the compressed spring. You can see the bolt running vertically right behind it.
In picture 3, you can see the top of the bolt and is marked with some yellow grease. The top of the bolt also has a notch to prevent it from declining too much. The plate that stops it is right underneath the notch and is barely visible. The black and gray plastic moldings act as guides for the bolt.
Pictures 1 & 4 are showing the whole mechanism, along with the strings that I used to compress the springs.
Picture 5 is the compressed spring with a good take on the infamous notch.
